FEEDING MECHANISM.

Specification of Letters Patent.

Application sied November 2a, 1912. serial No. 734,076'.

To (zZjwio/n it may concern.'

Beit known that I, CAREY A. CHESHIRE, a. citizen of the `United States, and a resident of the city of Des Moines, county of Polk, and Stateof Iowa, haw invented certain new and useful Improvements in Feeding Mechanism, of which the following is a specification.

M v invention relates to improvements in feeding mechanism and has for its object the provision `of improved feeding mechanism especially adapted for feeding articles having uneven or varying edges.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingl drawings forming a part of this specica-tion, and in which, v

Figure 1 is a side elevation of feeding mechanism embodying my invention, Fig. 2,

a central vertical section of the same, Fig. 3, a section taken on line .fc-:c of Fig. 1. Fig. 4, an enlarged detail view of a link employed in the construction, and v5, an.

enlarged section taken through the lower end of a stop member employed -in the construction.` i j,

The preferred form f construction as Iillustrated in the drawings comprises a re ciprocating feed plate l having stop members 2 on the rear end thereof which areadapted to engage the lowermost article 3 of. a stack of articles 4 resting on feed plate 1, as will be readily understood by those skilled in the art. A vertically' adjustable stop-plate 5 is arranged to contact centrally.

with the forward edges of the stack of articles but leaving' the bottommost article 3 p free to pass under said stop member. This s't'opmember is provided in its lower portion with a reciprocatory block 6 carrying a plurality of inwardly projecting points 7 adapted toengage the corresponding edges of the larticles 4, as indicated. The block 6 is pivotally connected to the lower end of an operating arm 9'which extends upwardly and isiixed to a pivot shaft 10 mounted in a bearing 8 on the upper portion of stop member 5. This shaft 10 is extended later-v ally to the ,side of the mechanism where'it is given an adjustable bearing 10. At lts outer end shaft 10 carries a downwardly extending operating crank arm 11 the lower end of which crries a pin slida-bry engaging a longitudinal slot 12 inthe end `of a by means of a pin 14 extending through a slot 15 in the side frame of the mechanlsrn.

11 and said link. By this arrangement, it will be observed, that as plate Lreciprocat-es, link 13 will operate arm 11 andconsequently ever 9 to reciprocate block 6 in stop` memer 5.

The arrangement is such that as plate 1 approaches the limit of its movement to the right, as shown in Fig. 2, the left setscrew 16 engages the lower end of arm 9 and rocks shaft 10 tothrow points 7 into engagement l'with the edges of. the`.articles 4. Then as plate 1 feeds tothe left, 2, carrying the lowermost sheet 3 with it, the upper sheets 4 are maintained in elevated positions by points 7 thus preventing their interfering` with the feed of the lowermost sheet 3. When plate l approaches the right hand set screw 16 engages the lower end ofv arm 9 and rocks shaft 10 to throw and permit the same to feed downwardly. From platelsheet- 3 passes to feed rollers .17 and thence to printing cylinders 18 or any other desired mechanism. This mecha-- nism will be found to be especially advantageous in the feeding of articles having uneven and varying edges, such for example, as cheaply and carelessly made newspapers which frequently have some of their edges This being so, when the sta-ck of newspapers rest on plate 1, these forwardly extending uneven edges on the two adjacent papers, will often not exceed in thickness a single paper. This being so the combined forwardly extending edges of the lowermost two of the stack'of articles could pass under the stop :member 5 simultaneously. But the taneously under the stop member, so that two papers whose forward edges have thus started to feed under the'stop member, will tend to'wedge or jamthemselves into the spacev under said stop member and thus render the feeding mechanism inoperative. However, by the construction above set forth, they points 7 will engage at least a Patented Nov. 4,1913.

link 13. Link is connectedwith platell Set screws -16 are arranged in link 13 and, are adapted to adjust the amount of play or Y lost motion between the lower end of'a-rmy as shown in Fig..

endof its movement toward the left, the

points 7 out of engagement with articles 4- extending well beyond .the other edges.,

bodies ofsuch papers cannot pass simulf portion of the article 4 next above the botf toxnmost article 3 and thus support the corresponding edge thereof and prevent this jamming action. 'l'he block 6 is extended high enough and provided with enough of the points T to .support several of the upper articles l thus relievin f j l the edge. of the next to the bottom article from all weight and pressure, which greatly facilitates the action above noted.

'hile I have illustrated and described the prel'ei're l ing my invention into ellect, this is capable of variation and modilication without departing from the spirit of the invention. l, therefore, do not wish to be ,limited to the precise but desire to avail myseltl of such variations and modications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure bv Letters Patent is:

l. Feeding mechanism comprising a .stop member; a reciprocatorv feed plate arranged to feed an article past said stop member; holding means mounted for cooperation with said stop member: and automatic means operable b v said feed plate. for moving'said holdingmeans torcngage the edge of an article resting against said stop member din-ing the feed of an adjacent article and to release said edge for l'ccd of the corres'pondinatl article, substantially- :is dt scribed.

2. Feeding mechanism eoniprisilg` a stop member; a reciprocatory 'eed plate arranged to feed articles` under said stop member; a blocli slidable in the lower portion of said stop member and provided with a plurality ot' projeciuie points adapted to form of construction 'or carry-- details of construction set ortln engage the edges of articles stacked against said stop member; and means for moving said block to cause said points to engage said edges during feed of an article and to Withdraw said points during the idle movement. ol. said feed plate. substantially as described.

:3. Feeding mechanism comprising a stop member; a reciprocatory feed plate arranged to feed articles under said stop member; a block slidable in the lower portion of said stop member and provided with a-plurality ot' projecting points adapted to engage the edges ot' articles stacked against said stop member: and means operable. by said feed platefor moving said block to cause said points to engage said edges during 4feed of an article and to withdraw said points during the idle movement of said feed plate, substantially as described.

l. Feeding mechanism comprising a stop member: a reciprocatory feed plate arranged to feed articles under said stop member; a block slidable in the lower por tion of said stop member and provided with av plurality of projecting points adapted to engage the edges of articles stacked against, said stop member; an upwardly extendingA lever connectcd'ivi'th said block; a pivot shalt for, said lever; an operating arm on .said fha'tt: and an adjustable link- Connell' 4tion hein-een said arm and said feed plate,

substantially as described.

.ln testimony alici-cot' l have signed my name to thisl specification in the presence of two subscribing witnesses.
